An improved hybrid method of backward shooting and bouncing ray (SBR) physical optics (PO)/physical theory of diffraction (PTD) is proposed to investigate the backward scattering from a three-dimensional electrically large target. The basic idea is to combine the forward-ray-tracing technique to accelerate the original backward-ray-tracing one. The proposed method significantly reduces the computational...
In this study, we firstly take good advantage of SEER Public-Use Data to predict breast cancer recurrence using data mining techniques. The SEER Public-Use Data 2005 is used in this research. We presented a new data pre-classification method and firstly find a possible solution to discover the information of breast cancer recurrence of SEER data. After the preprocessing of the dataset, we investigate...
